` Beit known thatl, ALFRED J. SMITH, oi the city `and county of Sanflranoisco, State of California, have invented an Improved Water-Closet Valve and I do herebydeclare the following description and accompaappertains to make and Yuse my said invention or i improvements Ywithout further invention or` experi- The objeetof my invention is to provide an improvement in `that class of valves which is employed to `admit a 4limited quantity of `waterl to` the vbasins in waterfclosets for :thepurpose lof cleansing 'them and `It consists of an automatic'airangement of valves, *which are operated bythe weight of the person upon `the seat, so that, after the weight is removed, the

` valves will act and` allow the water to flow into the basin for a length oftime which is regulated by their adjustment. g Y 1.` Referring to the accompanying =drawing for a completeexplanation of my invention-f#-Y `Al is a hollow cylinder, made ornamentaL'acGQEdin g to taste-and havngran ingress-pipe, B, and an egress- `pipe,*0,openihg into it near the `lower end, as shown.

" A short 4chamber,with two seats, is made between y these twokpassages, andthe lower end of the short liollowcylinder D serves as avalve, which rests upon the upper seat.

The `lower seat is closed by a valve, E, which is held in its place by the spring E.

y The cylinder D tits looselywithin 4the outer oase and is `kept downby a spring, G, which presses upon the cover aof` the cylinder, while the upper end of the springrestsagainstthe plate H.'

`This platehas a'stem,I, and `is moved downward so asto compress the spring G bymeans of the rod J, .which is pressed down `upon it by the weight of the person usin the seat. y

passeslthroughthe cylinder D,` moving water-tight through the lower end b of the cylinder,

f which forms the upper valve,`before described, and extending some` distance above the top ofthe cylinder d Dand inside the spring G, so that, .wheiii the spring G Y is compressed, the plate H will strike the top of the y stem'K and 'press it down.l When this is done the` springl G willkeep the upper valve closely against the seat-,and the stern K being pressed down through the cylinder l), its lower end will force the lower valve E away from its` seat, thus leavingthe lower end oi the vpassage open;. but no water can, flow, as theupper end remains closed by the valve b ofthe cylinder D.

` `nying `drawing are suflicientmto enable any person skilled inthe art or lsciencegto which it most'nearly The stein K carries a piston, L, which moves closely within the cylinder D, and when the stern K is forced down, as above described, this piston will move to, the bottom ofthe cylinder. When the weight ofthe person is removed and the compression of the spring G ceases, the elasticity of the spring F and the force of the water will raise 'the valve b` from its seat-by its pressure against the valve E and the lower end of the stem K.

l Q The stem K will lift the whole of the cylinder D, because the piston L fits so tightly that it will only moveto the upper end'of the cylinder again by the gradual passage of water from the main barrel into the cylinder through the small hole S at its lower side, this being assisted by the ftension, of' the spring M, which surrounds the stem K, inside the spring G, and presses against a nut on theupper end ofthe stem K till the piston has arrived to its posit-ion at the top ot' the cylinder. Y

'lhe cylinder D strikes the shoulder o as it rises, so that the lower valve E is also kept open by the stem rKtill the piston L has arrived at the top 'of the cylinder. closing slowly, so that the water is allowed to ow through the pipes and() into the bowl `during the interval in which the valves remain open.'y The springs can be so adjusted that the valves will remain open 'any desired time before shutting off the water,

`the iiowinto thetbasin being thus easily regulated.

4Having thus described my invention, l

What l claim, and desire to secure by Letters Patent, isy I y 'lhe compressing-spring G and cylinder D, in cornbination with the valve b and stem K, when these Several parts are arranged and operated substantially as and for the purpose set forth.

In witness whereof' I have hereunto set my and seal this 10th day of December, 1870.

ALFRED J. SMITH. [L. 5.]
